How much lift are you looking for? Depending on height, what about incorporating a trailing arm on a shackle into a lift block. You could use 2x3 tubing or so if that would give you the lift you need and run a length of that tubing up to a shackle mounted on the frame or a crossmember up front of the axle. If it was enough lift, it would also help with axle wrap and not sacrifice any movement of the stock suspension
